Yes, "Always on Top" seems to work. There's a minor gotcha though. I found that if I enter a flight and then Alt-Tab out of FSX, when I Alt-Tab back to FSX, TB and FSX are fighting for the second video display (they flicker back and forth, and also mess up the textures on the main display). This only occurs when I'm in an actual flight. If I exit the flight back to the FSX main menu and start a flight again, it's all OK. Not surprising because exiting the flight causes FSX to revert back to a normal single display mode vs. blanking all the displays.

This may depend on your video card/drivers (or maybe even specific setup of those cards and video ports). I have a pair of nVidia 8800GT cards, with one monitor on each video card. Of course, SLI is turned off.

Yes, FSX takes over all monitors (and hence blanks unused monitors). This allows you to bring up the GPS, or a 2D cockpit and drag it to the second monitor without using the Windowing functions like FS9 used to do it. In fact, with a touch screen as my second monitor, if I drag the 2D cockpit panels onto that 2nd monitor, I can click the buttons and knobs offering a functionality similar to Touch Buddy, but not as advanced obviously because I don't have complete control over the layout of those panels. For example, the 2D main cockpit panel is too large making most buttons too small and difficult to click with a finger. If I import those 2D cockpit panels into TB and re-arrange them, I get better visuals and control. I haven't done this yet, but I plan to start playing with it soon.

Another downside to trying to use a touch screen with the FSX 2D panels is every time you start a new flight, you have to always bring them up, drag them into position, and re-size them. Very annoying. TB will make this aspect much easier.
